Remarks
A cell stores its text formatting settings in the CharacterProperties property. Call the cell’s ChangePropertiesAsync method to change the font size of all cell characters.
The following example sets the font size to 16
for all characters in a table:
<DxRichEdit @ref="richEdit" />
@code {
DxRichEdit richEdit;
protected override async Task OnAfterRenderAsync(bool firstRender) {
if (firstRender)
try {
await InitializeDocument();
}
catch (TaskCanceledException) { }
await base.OnAfterRenderAsync(firstRender);
}
async Task InitializeDocument() {
/* Surround the code that contains an asynchronous operation with a try-catch block to handle
the OperationCanceledException. This exception is thrown when an asynchronous operation is canceled. */
try {
var columnCount = 4;
var rowCount = 5;
richEdit.DocumentAPI.BeginUpdate();
// Creates a table
Table myTable = await richEdit.DocumentAPI.Tables.CreateAsync(0, columnCount, rowCount);
for (int i = rowCount-1; i >=0 ; i--)
for (int j = columnCount-1; j >=0 ; j--) {
var cellPosition = myTable.Rows[i].Cells[j].Interval.Start;
await richEdit.DocumentAPI.AddTextAsync(cellPosition, "sample text");
}
// Customizes the table
myTable = await richEdit.DocumentAPI.Tables.GetAsync(0);
foreach (TableRow row in myTable.Rows)
foreach (TableCell cell in row.Cells)
if (cell.CharacterProperties.FontSize != 16)
await cell.ChangePropertiesAsync(properties => {
properties.CharacterProperties.FontSize = 16;
});
richEdit.DocumentAPI.EndUpdate();
}
catch (OperationCanceledException e) {
Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
}
}
}
